I've had some great days at Vail closing day. Even lower at Beaver Creek too.
First, you need enough snow, and we've got that. Then you just need a day when the temp and sun are just right, not too warm, not too cold. On the occasional cold day, the surface conditions may actually be better lower at Vail then up at Breck where it could be icy.
It's a lot like A-basin at the last couple weeks of May, and we enjoy that, yes? It depends on the weather, but Vail could be great this April with all the snow.
Above say 11k there are gobs of snow its awesome.
